The risk is pretty high, too. Instead of a $300 p-trap replacement, you can do it yourself, but if you do it wrong, you can have 4-5 figures of accidental water damage to the house.
Absolutely! And that's just in your bathroom wear-and-tear maintenance.
Never mind commercial plumbing! Small business owners trying to sort out a commercial block backup caused by a grease-trap failure could start to turn out a few issues...
Plumbers deserve higher regard than they're given (all great plumber jokes aside).
That said if the tech could be used to improve the training of specialists in remote areas/ areas that might be short a few journeymen or master tradespersons, or aid in especially complex problems, it could be a huge boon and reduction in cost (eg - travel costs).
